Programming Overview

You assign logical addresses to instructions from the highest level (element) to the
lowest level (bit). Addressing examples are shown in the table below.

Bit files are bit stream continuous files, and therefore you can
address them in two ways: by word and bit, or by bit alone.

Some programming devices support short addressing. This allows you to eliminate the file number and file
delimiter from addresses. (For example: N7:2=N2, T4:12.ACC=T12.ACC, B3:2/12=B2/12
)
Consult your
programming device’s user manual for information on addressing capabilities.
